Multi Emulator Super System (MESS) is an emulator for many game consoles and computer systems, based on the MAME core. MESS emulates portable and console gaming systems, computer platforms, and calculators. The project strives for accuracy and portability and therefore is not always the fastest emulator for any one particular system. However, its accuracy makes it useful for homebrew game development.
MESS supports 668 unique systems with 1748 total system variations and is constantly growing. However, not all of the systems in MESS are functional; some are marked as non-working or are in development. MESS was first released in 1998 and has been under constant development since.
This item contains the BIOS ROMs necessary for the operation of the MESS Emulator with nearly all its supported platforms.
